IMO, it is in dense soil - not very good drainage. I believe I see signs of waterlooged leaves. The pot is one of those hanging pots that have 'raised' drainage hole, isn't it? Did you use the insert that keep soil above it? Even so, water collected will be reabsorbed back and that means wet feet for the plant (I use same pots, but drill quite a few holes in the low part).

If my plant, I would repot into much grainier mix that would offer drainage and air exchange. Pup should be potted into the same mix. They don't need to be watered too often, and the plant should be in good light. If in poor light now, introduce into more gradually.
